VARIO – easy to operate

Let’s start with the main features:

  • stackable desk device with master-slave function
  • Leakage monitoring
  • Multi-channel control system for 4 to 32 zones in steps of 4
  • – 230V / 16A per zone
  • Software updates per download
  • Display can be swiveled up and down

Central control 4.0 – VARIO is the future

One visualisation – one operation: Despite its size, the handy VARIO turns out to be a highly user-friendly, efficient hot runner control device, thanks to its display that can be swiveled up and down. Two desk devices with up to 32 zones can be combined with each other via the master-slave function and controlled per touch panel through just one device. In addition, connecting further devices, including needle valve-control and pressure measurement system, is possible via standard Ethernet connection. The VARIO with microcontroller control meets the highest requirements for the process reliability of your plastic manufacture while remaining as small and handy as possible. A further step towards the future is the linkage of all hot runner controllers to a central mould server within your company network or via OPC/UA.

The structure

User interface:

Thanks to its practical carry handles, the stackable hot runner control device can easily be transported. All fuses are easily accessible from outside.

  1. touch panel that can be swiveled up and down
  2. USB connection
  3. Power button
  4. Fuses

Device rear view:

We will manufacture the mould and network connection according to your individual company standards.

  1. Mould connection – custom-made for you
  2. Power supply – custom-made for you
  3. Ethernet connection
  4. Alarm contact
  5. Ext. Reduction and boost

Possible combinations:

All device data and mould settings can be centrally stored and managed via the Ethernet connection. Furthermore, additional devices such as needle valve-control NVS and pressure measuring system DMS are linked with the devices via the Ethernet connection. These then perform the operation and visualisation. Various injection moulding machines can be connected via conventional data interfaces or via the Ethernet so that operation and visualisation occurs on the machine’s screen.
